Hyper-V Feature Request: Promiscuous Mode

You know what they say about making assumptions?

This should apply doubly to Microsoft software.

Getting all excited about trying out the new release of Security Onion, I setup a SPAN on my core switch, and sent it to a virtual NIC on my new Hyper-V server.  For some reason, I could see the traffic on the host OS, but never on the guest OS.

After doing some searching online, I found out that, unlike VMware and ESXi, Hyper-V does not support Promiscuous Mode.

That really sucks.

Microsoft, your forcing my hand….  Back to ESXi for my network monitoring server.

    MS has something similar they allow you to mirror the traffic of a guest nic to another guest nic but they do not have a switch level option unless you use a adv virtual switch like the Cisco nexus 1000
